Introduction
For high speed application provides measurements at 2KHz with 200 packets per
second containing 10 x 32 bit values representing nano volts/volt. The T24-SA is
a high performance strain gauge to radio telemetry converter module, offering
precision measurement with high performance two-way telemetry.
Usable around the globe on licence-free 2.4GHz frequency, the T24 range
avoids local radio interference to ensure data integrity and security. For use in
any measuring applications, from torque to weight, vibration to flow, the T24
offers users a complete solution to your measurement requirements.

The modules form part of a simple measurement system that offers the opportunity to
collect measurements from a variety of sources, enabling accurate and immediate
data collection without the requirement for extensive and labour intensive cabling
operations.
The wide temperature operating range and the robust technology ensures that the
module it is not susceptible to harsh physical or electrical environments.
Options include internal or external antenna.
